摘要： The invention describes an X-ray tube for generating X-radiation, wherein the tube comprises a rotary structure, which comprises a rotating anode, a stationary structure for rotatably supporting the rotary structure, a hydrodynamic bearing, which is arranged between the rotary structure and the stationary structure, wherein the bearing comprises a gap between the rotary structure and the stationary structure, means for stabilising the dimensions of the gap with respect to distortions because of thermo-mechanical causes. A further aspect, which is described, is a method for manufacturing the tube according to the invention, wherein means for stabilising the dimensions of the gap are arranged. It is also described an X-ray system for diagnostic use comprising the tube according to the invention, wherein the X-ray system is adapted to stabilise the dimensions of the gap. Another aspect of the specification is a method for manufacturing the X-ray system.

摘要： The invention relates to a rotary-anode X-ray tube which includes a sleeve bearing having an axial bearing section and a radial bearing section. Furthermore, radial sealing sections (601, 602) are provided in an outer bearing member (605, 607, 608) which have no functional relation to the axial bearing surfaces (2012) of the axial bearing section. Thus, additional sealing principles like gaskets or sealing edges can be used although this may result in degradation of surface parallelism.

摘要： In a rotatable anode (4) of an X-ray tube, a heat transfer between the rotating disc of the anode (4a) and the second bearing element (11) is achieved by providing a contact material (14) within a gap (16a, b) between the anode disc (4a) and the second bearing element (11). Contact elements (15) protrude from the second bearing element (11) into the contact material (14), thus allowing a heat transfer from anode disc (4a) to second bearing element (11) via contact material (14) and contact element (15).
